Hi
I am an Iranian that is traveling right now, I want to go to China this April and I want to apply through my friend in Malaysia , I can get my visa when I am in Malaysia before going to China, so the questions are:
1. Can I apply a Chinese Visa by my friend in Malaysia?
2. I Have planned to be in China for 25 days, so what kind of visa should I apply?
3. How much will it cost me?

Thank you in advance for your kind attention.
